Abstract
About one in every five drivers will have a deficient capability in one or more of the following visual tasks: detection of obstacles, delineation, and signal lights; temporal resolution of flashing and flickering lights; spatial resolution road signs legends and symbols; and colour discrimination. It is argued that the visual requirements imposed by licensing authorities do not (and should not) exclude these drivers from holding a license to drive; rather, road design-should compensate for defective vision. Discussions and author's closure are included.
